Q: Do you ever wish you could read Harry Potter again for the very first time?

A: Yes, and here's how to do it.  There's both a physical and a mental (self-hypnosis-type) component to the technique.  We'll explain how the physical component facilitates the mental.  Acquire from another nation a copy of whichever Harry Potter novel you wish to read again; for example, if you first read an American edition and wish to stick with English, seek a copy of the book that was printed in the U.K., Australia, Canada, or so on.  This new copy will look and feel different from the one you first read, and that's crucial for truthfully telling your subconscious mind that you have never read this particular book.  Indeed, to read Harry Potter again for the first time will require a sly bit of auto-hypnosis, and it's far easier to begin by not lying to yourself but rather affirming that you truly never before have opened the book you are now holding.  Sitting comfortably with eyes half-closed, gaze upon the closed book in your lap and concentrate upon the "fact" that you have heard of Harry Potter but have never read any of the books.  Your willpower, focused for half an hour at a time, will lead your mind to believe that you are new to the Harry Potter saga.  Interestingly, there's a strong argument that authors like J. K. Rowling write their books in a state of self-hypnosis, due to the combination of intense concentration and the need to conquer the authorial ego so as to get in touch with the personalities of the story's characters.  "Every author knows the difficulty--in some cases impossibility--of dropping a story until it is finished.  He is under control of the idea, and can remove the obsession only by finishing the story.  Then he awakens, or partly awakes, for a time--until the next idea comes along" (Morgan Robertson, "The Self-Hypnosis of Authors," The Critic, 1906).  And so, like J. K. Rowling as she originally wrote her stories, you must concentrate and conquer the ego that believes it knows how it all turns out.  When Rowling was first inspired to write the original Harry Potter story, she had an outline in mind for how the events would unfold, yet when it came time to pen the very first word, to communicate the story properly she had to think like her future readers, unknowledgeable of how it would all turn out.  She had to approach the story in her head with what the Zen Buddhists call a beginner's mind.  If she could do this as the author of her own novels, you can do this as the reader.  You were once brand new to Harry Potter, and that mental state yet exists in your memory.  Make a concerted effort to reclaim that state of mind.  Tell yourself again, again, and again that you are a newcomer, until you're ready to open that new book.
